Negative. Further, you can bash me now for saying so but I guarantee you that if you puff a 496 you will live to regret it... That engine is not made for it. The pistons are very brittle on both, the 375& 425 models.

Also, you need to know if you have a steel crank or cast. If I remeber, they started with steel; went to cast; back to steel on some serial number range; and then went back to cast. It's a great, reliable engine but she don't like blowers for too long...

In all sincerity, I do wish you luck and I'd like to hear that you came back 2 seasons later and had no issues worth mentioning after running a blower on this motor.

take care,

Don't forget that the ONLY difference between the mag and the mag ho consists of 3 things:

1. Size of throttle body
2. Cam
3. Computer program

I still have all of these items laying on the shelf too.

How does it go again?....

Don't finger fack us with details!!!!!

He was talkin to whipple about a 6# kit with a new program for the computer. They really hyped over the performance but never once mentioned longevity!

We run 20-30#s of boost in race cars but never in boats. Being that boats are always under a load, its a whole different ball game, even at 6psi....

I installed a whipple that pumps around 5-6 lbs of boost on my 2008 496HO . I ran the boat in several poker runs and ran the boat hard all summer averaging between 4500 - 5300 rpm most of the time and the boat performed flawlessly with over 50 hours prior to the whipple and over 125 hours with the whipple. I would highly reccomend the whipple it proved to be very reliable and the power that it cranks out is amazing. If you go on whipple's site I believe it's around 645HP not bad for a weekend bolt -on.My top end went from 72 gps on friday to 82 gps on Sunday.

Yup there ya go see post #5, I was close!!

They both have hyperutectic pistons. I'm not sure about the crank and rods. I think they have varied from year to year and not sure hwats in each particular year.

Kevin, how are you?

I thought I heard that you were looking for an engine sometime recently???

Doing good thanks , Hope you had a good summer.

I'm actually looking to pull the motor in a couple weeks and and do a motor rebuild . I'm looking to run a little more boost and do a few upgrades cam & exhaust and maybe heads if I can swing it . I'm looking to get to around 700 hp . And maybe see 85.
